Work is underway to make GRUB less BIOS-dependant on its disk access
routines (see disk/ata.c, recently committed).  However, you can't
completely do without it since you need to load GRUB itself somehow
and AFAIK a full ATA driver won't fit in the first sector.

If you want to get rid of BIOS completely, look at LinuxBIOS project
